To all whom, it 'may Concern.'

Be it known that I, THOMAS Sturm; a, citizen ot the l'nited States, anda, resident of the city of York` in the count,r of York and State ofPennsylvania, hartJ invented a certain new and useful Improvement inAir- Blowing Fittings with Internal Cleaning-- W'ire, of which thefollowing is a specifiestion.

My invention relates to apparatus for the manufacture ot iee from rawWater under what is known as the high pressure air systeni, in which airat a comparatively high pressure, say troni 1S to 20 pounds pressure,after being delnuniditied, flows into the water to beI frozen through atube fixed in the ran containing the. saine, eontiiuionsliv throughoutthe freezing operation. ln apparatus of the kind in question, a definitepressure agitation ot the water in the. freezing Cans during theFreezing operation. Not only, however, is the use of more air than isabsolutely necessary tor this purpose uueeononiieal in that thecompression of an unnecessary amount of air is a waste of power, but itis positively detrimental in. that it is liableT by undue agite;- tionof the water, to cause. it to spill over the sides of the can, the lossot which water not only decreases the desired Weight of the ice cake butalso weakens the surrounding brine.

An oritiee to allow the passage, only ot the amount of air requisite forthe proper agitation ot the water would. however, he very small, sayabout l/l of an inch in. diameter. would take time and money; and thisminute passage, after it was formed, would be very liable to becomeelosed or clogged up by toreign matter such as dirt, scale and the like,thus impairing materially its usefulness for the purpose for which itwastlesigned.

lt is the object ot my invention to pro. vide means which, while adaptedto deliver only the predetermined amount of air under pressure requisitefor the proper a'V of the Water in the can during the freezingoperation, shall be tree 'from the objections above named. To this endmy invention consists of the devices and eombination of devices whichwill first be described in connection with the accompanying drawings Todrill such a minute passage ltation Y forming part of thisspecification, and will then he more particularly pointed out in theclaim.

lgure l is a View partly in longitudinal Vertical section and partly inelevation of so mneh of a. freezing can, and an air lateral from themain compressed air yheader not shoivn) as is needed for purposes ofexplanation, together with the connections between said air-lateral andthe vertical air tube tilted on said can.

Fig. 2 is a cross sectional view illustrative of the Iranner in whichthe, vertical air tube is seated in a groove on the outside of the eau.

L is an air lateral, which in practice is eonueeted to and draws itssupply of air 'from a main air header whieh usually runs lengthwise ofthe brine tank in which the freezing Cans are assembled; A is a T thevertical tubular limb ot which enters the air lateral from below andsecured therein by a screw threaded joint. @Zat-h horizontal braneh otthe T A is provided with a rubberlined linen or other suitable hose ll,to the metallic nozzle-like fitting which eonneets it with the air tubeon its appropriate freezing can. As the connections for each branch o'tthe T are the same, only one comple-te set is shown-that for the righthand branch. Each piece of hose is fitted onto its branch of the T Awhere it is held by means of external annular eorrug'ations on the endof the branch over which the end of the hose is drawn. The elasticpressure of the. hose upon the brunch prevents leakage', but, it suchelastio force be not Suid nient, it can be supplemented by any suitablemeans which will assure oomplete stoppage of leakage as for example. abinding of coper Wire tightly wound upon the exterior of that portion ofthe hose which envelope the branch. At the opposite end of the hose is ametallic tubular elbow fitting B which is designed to receive theCompressed air and to conduet and disehargge it into the air tube Tfixed to the freer/,ing can 'F'. The receiving end of this nozzle-likeelbow littinl has anannularly corrugated exterior which is fitted intoand secured tightly in this end n? the hose precisely as in the branchof the T A at its other end.
